Soren, I can tell you where to put the +/- coils go and an example about the four digit code! (No really I'm serious about it.) where the second switch is in the grey room, put the fork in the cut wire to complete the circuit. Then pull the switch and a ladder will come down. Climb the ladder twice. Then look on the left and the right you should see indentations in the walls. Next go into the left and go left again there should be a secret. Finally go into the right and go right again then you should see 2 empty holes, put the +/- coils in the hole and your done with the coils! Heres an example,

THANK YOU JAN.JAN!!!! you are very nice. i've seen a lot of your help comments before. but i just tried the number 8673 (m=867) and the light was still red! =) (by the way i'm not mad at you jan.jan =] )

if you're stuck on the 4 digit code then you get your diary which says on mine m=601 and on the power thing in the red part says c=2 so 2x2 =4 4x601 mine was 2404 but they change each time so dont copy my numbers

I passed the second floor, I got all the way up, and there is no switch box, no broken wire to use the fork on. I climbed all the way down and checked every room and got all the way up again and still nothing!

So you have moved the ladder above the grey, second floor room from horizontal to vertical? If you have done that then at the top of that ladder there should be the broken circuit where you use your fork etc. If you haven't shifted the ladder yet then you have to find, attach and use the switch handle in a tunnel first.

easy e
What works for me is to

just keep plugging away at it. It probably helps to only use 1 button i.e. get 2 prongs into position first then use 1 button to make the other 2 prongs go around and round until they fit.

When I enter the first sewer portal to the left in the beginning of the game, the tunnel is just completely dark. I go as deep as I can until the hand stops pointing but I can't go the other way to get the key at the end. I can turn back and go out theway I came, but I can't get the key from the top part of the pipe. This is very frustrating. All of you have gotten the key but I can't get it.

The key that you are looking for is to the far left of that sewer, not in the one above it. You will get the key from the pipe above later. You also might want to brighten your screen a wee bit - you won't be able to see a thing otherwise and there a lot of pipes to have a go at later.

Those who has problems with where to put the negative and positive coils (I had trouble with this too >.<).

At the metal tower,start by the first part to go to the treleporter room.Go up twice till the room is cone shaped,if you look a bit right and left from the ladder,you see the tiles are actually crawl tunnels!OMG,crawl through the left to find a secret,go right to find the place to put the coils..

The positive coil goes in the + tube and Negative coil in -.If you didnt sudy batterys enough you wouldn't know that..

Getago : Einstein came up with the idea that energy and mass are actually the same thing! You can convert one into the other. And the incredibly simple formula of how to calculate the amount of energy which corresponds to a given mass is

E=m*c²
E = Energy
m = mass

Now, unlike in this game the very last term in this formula is actually a physical constant, namely the speed of light (in vacuum).
How odd, no?

Mass times the square of the speed of light equals energy.

The uniqueness of this formula cannot be stressed enough.
However, up to now it works as a good theory.

YESS!!! I've done it!!
Well, I needed a little help for a couple of things... but still!!
I've played the original Submachine and the Ancient Adventure, and finished them right away, but this one gave me a little bit of trouble... specially in the large sewer, I kept getting lost and voyaging in circles, haha. I only managed to find 16/20 secrets :(

I wasn't sure exactly how that set up Submachine 3: the Loop. Oh well. It was pretty kul overall. Ending could've been better, and it was hard, but with the walkthrough, it was fun. :)

If anyone here hasn't play Submachine 4, go play it now. Actually, play Sub 3 first, then Sub 4. Sub 4 is most like Sub 2, but has areas seen in all the mainstream Submahine games (0, 1, 2, and 3; Submachine FLF is it's own small story, so it doesn't really count)

I was going to write a walkthough - but in the middle i just said, "what's the point?" and stopped - "i want to get on with the game!". And so instead the excitement permitted me to delete my half-writtenwalkthrough, and finish the game. And it was worth it. Submachine rules! Maybe i'll write one later...

so....that plaque near the alcove....
i believe also that those symbols are irrevelant...but..justa joke...cuz those symbols are from submachine future loop....
just a littlebit of info for all of you..lol

I walk into the room and apparently the code from the lighthouse picture is already set in the machine. I press the green button and nothing happens. I'm not sure if there is anything else I need to do to trigger the machine.

HELP! I put the fork in to complete the wires, pulled the lever, the ladder dropped down...but there's stil nowhere to put the +/- coils! If I climb up twice like people are saying,it just takes me to the lightbulb room. Is that where they go? I can't seemto get them to go anywhere!

I seriously need desperate help very bad!!First:Where do I put + and - coils at?
Second:Where is the key for the little cut out
area with the lock on it at the very tip top
of the lighthouse?Third:I've got 14/20 secrets,where are the rest of them!?!
